To all 'whom t may concern.:

Be it known that we, ALBERT E. COOK and THOMAS VAN TUYL, citizens of the United States, and residents of the lcity of Evanston, in the count of Cook and State of Illinois, and of t e city of Kankakee, in the county of Kankakee and State of Illiinvented certain new and useful Im rovements in an Extensible Frame for ombination Motor Vehicles; and we do hereby declare that the followin is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numovable therewith merals of reference marked thereon, which form a part of this specication.

This linvention relates more particularly to a double three-point suspension frame for use on combination motor vehicles, and constructed to permit the same to be extended j or shortened as desired.

It is an object of this invention to provide a vehicle with an extensible frame'.

Another object of this invention is the construction of an adjustable telescoping frame ada ted to be' removably attached to a motor ve icle. j

`Alfurther object of the invention is the construction of an extensible frame adapted to be removably attached to a vehicle frame and permitting the rear drivin mechanisms of said vehicle to be supporte thereon and when adjusted. .1. lIt is [an important object of this invention toconstruct a two-section telescoping frame adapted to be attached to a vehicle frame toy support the ,reardriving mechanisms in op I erative connection with the vehicle motor.

It is also an object of the invention to Aprovide a power vehicle with a three-point suspension extensible frame and an extensible driving shaft.

It is furthermore an object of this invention to provide a three-point suspension motor vehicle with a.y three-point suspension tractor or truck attachment to prevent torque from the attachment section from being transmitted to the vehicle section.

It is afurther object of the invention to construct an adjustable combination vehicle ywith an extensible shaft mechanism and brake rods. i j

Other and further important objects of this invention will be apparent from the disclosures'in `the drawings and specification.

v vehic Ther invention gin a preferred form) is illustrated in the rawings and hereinafter more fully described.

Figure 11 is`an enlar d 'det-ail section taken on linellll of Bgiegure 5.

As shown on the drawings thereof partly The `reference numeral 1 indicates an au-y ydriving' shaft 6,'is tubular and of rectangular cross section.

The automobile brake rods are indicated by the reference nu- -or theA 'meral 7, and said brake rods are adjustably connected with brake tubes 8, the rear ends of which are connected ,to the rear brakes 9. Clamping members 10 are provided for holding the brake rods locked in adjusted position with respect to the brake tubes 8.

Rigidl secured to the front end of the chassls ame sills are the arms 'of a U- shaped angle bracket or support 11. A horizontal `pin or stub shaft lf2 1s supported cen-` trally in the bracket 11.

Engaged on the outer projecting end of the pin 12 is the lower end of an upright arm 13, the upper end of which is rigidly securedto the middle vportion of the front crossbar 14 of an extensible lthree-point suspension frame. The

'extensible frame Fcom rises two adjustable telescoping sections.

e front or forward l depressed rigidly holding two section embraces the crossbar 14, to the ends of which are rigidi secured the front ends of channel side sil s 15, which are rigidly connected together by pairs of cross braces or plates 16, 17 and 18. Each of the front section sills is provided with a longitudinal row of openings 19.

lThe rear frame section comprises channel side sills 20, the rear ends of which are rigidly connected together by a centrally cross bar orbrace 21. A transverse brace 22 is also used to connect the sills 20, near their front ends. Each of the rear channel sills 20. is provided with a longitudinal row of openings 23. An 'apertured channel member 2t is riveted in the rear portion of each of the front channel sills 15. Bolts 25 are used to removably connect the front and rear frame sections 1n an adjusted position. As clearly shown in Figure 11, hooked channel uide members 26 are secured to the rear s ls.20, with the hooks 27 engaging around the flanges of the front sills 15.

As shown in Figure 8, a supporting member 28 is secured centrally between the upper and lower cross braces 16. VSecured to said support 28 is the rear end of a horizontal stub guide shaft 29, thek front end of which slidably projects through a guide support 30 secured between the upper and` lower cross braces 17. A collar 31 is secured on the front end of the stub shaft 29. Enga ed on the front portion' of the shaft 29 etween the collar 31 and the support 30 is a sleeveof a hanger 32, which supports the rear endlof the automobile chassis frame 5,', aording a three-point suspension for said chassis frame. Secured on the bottom of the lower cross braces 16 and 18, are supports 33, for parallel spaced guide rods 34 in posltion. Slidably engaged on the rods 34 is a hanger 35, provided with a dependin sleeve 36, through which a cylindrical riving shaft 37 slidably projects. The shaft section 37 is provided-with A a rectangular longitudinal passage for slidlar shaft tube, into which the main driving shaft tube 6 telescopes, thereby providing an extensible driving shaft mechanism for the vehicle. rihe rear end of the shaft section 37 is supported in a bearing ybracket 39,

ably receiving an intermediate rectangu secured on the bottom of the' transverseV 40' conbrace 22` A vuniversal coupling it the autonects the rear shaft ysection 37 w mobile dierential.

The operation is as follows:

In Figure 1 the dotted lines disclose the normal position of the rear wheels 3 of a motor vehicle. When the vehicle is equipd with an extensible three-point suspension frame of the type described, the automobile rear driving mechanism is supported on the rear portion of the rear extensible frame section ,20--21 as shown.- The brake rods 7 are adjustably connected with the auxiliary brake rods 8 to permit operation of the brakes 9. rlhe drive from the vehicle motor is transmitted to the rear driving differential mechanism 4 by means of the extensible telescoping shaft sections 6, 38 and 37.

The combination motor vehicle is of a double three-point suspension type, the extensible frame being supported at its front end on the short shaft member 12, and at its rear end by the two wheels 3. The automobile frame 5 is supported at its front end by the two front wheels 2 and at its rear end by the hanger bracket 32. This construction of the frame sections prevents the transmission of torque lfrom the extensible frame to the automobile frame 5.A

The front and rear sections comprising the extensible frame are slidably connected with the front sill members 15 telescoping into the rear sill members 20. The extensible frame sections are adapted to be adjusted with respect to one another and then locked in said adjusted positions by the locking bolts 25, which are adapted to be vprojected through the re lstering openings 19 and 23 of the frame si ls. The telescoping drivin sha-ft and the brake rod members are a justable with the adjustment of the extensible frame sections.

From the novel construction disclosed it will be noted that considerable variation in the length of the three-point suspension extensible frame is permitted by simpl removing the bolts 25 and sliding the rame sections with respect to one another until the desired length is reached. The frame sections are then bolted together.

It will of course be understood that. numerous other arrangements may be provided for permitting longitudinal adjustment of the extensible frame sections to vary the length of the `motor vehicle.

We are aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and we therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

We claim as our invention:

1. The combination with a Vehicle chassis frame, of an auxiliary frame, driving wheels supporting the rear end ofthe auxiliary frame, a one point suspension bracket connecting the front end of the auxiliary frame with-the front end of the chassis frame, front wheels supporting the front end o the chassis frame, and a one point suspension bracket connecting the rear end of the chassis frame with the auxiliary frame.

2. The combination with a vehicle chassis frame, of an extensible auxiliary frame disposed thereabove, wheelsV supporting said frames, and one point suspension brackets at both ends of one of said frames for connecting said frame to the other.

3. The combination with a vehicle chassis frame, of a truck attachment frame, and one point suspension brackets at the opposite ends of said chassis frame for connecting the same to said truck frame.

4. The combination of two vehicle frames each supported at one end by two wheels, and a support at the opposite end of each frame connected to the other fra-me to form a. vehicle embracing two three point suspension sections.

5. The combination with a vehicle frame and motor, of front wheels supporting the the auxiliary `frame to the front end of the vehicle frame, a one point support mechanism connecting the rear end of the vehicle frame to the auxiliary frame, driving wheels supported near the rear end of said auxiliary frame, an extensible driving shaft connecting the motor with said driving wheels, brakes on said drivin wheels, a control lever for said brakes, andg extensible brake rods connecting said control lever with said brakes.

In testimony whereof we have hereunto subscribed our names in the presence of two subscribing witnesses.
